EEGLAB安装及测试.docx

1. 在MATLABR2015a中添加EEGLAB工具箱的问题 eeglabWarning: MATLAB has disabled some advanced graphics renderingfeatures by switching to software OpenGL.

If no arguments, pop up an input window. Usage: EEGOUT = pop_loadset; % pop up window to input arguments EEGOUT = pop_loadset( key1, val1, key2, val2, .); EEGOUT = pop_loadset( filename, filepath); % old calling format Optional inputs: filename - string dataset filename. Default pops up a graphical interface to browse for a data file. filepath - string dataset filepath. Default is current folder. loadmode - all, info, integer all - load the data and the dataset structure. info - load only the dataset structure but not the actual data. integer - load only a specific channel. This is efficient when data is stored in a separate .dat file in which individual channels may be loaded independently of each other. default: all eeg - EEG structure reload current dataset Note: Multiple filenames and filepaths may be specified. If more than one, the output EEG variable will be an array of EEG structures. Output EEGOUT - EEG dataset structure or array of structures Author: Arnaud Delorme, CNL / Salk Institute, 2001; SCCN/INC/UCSD, 2002-(2) EEGLAB可导入的数据类型MEX从字面上是MATLAB和Executable 两个单词的缩写。.MEX文件是一种可在matlab环境中调用的C（或fortran）语言衍生程序，MEX文件的后缀名按32位/64位分别为 .mexw32/.mexw64。(3) ERP事件相关电位（ERP，event-related potential）是一种特殊的脑诱发电位，通过有意地赋予刺激以特殊的心理意义，利用多个或多样的刺激所引起的脑的电位。它反映了认知过程中大脑的神
